flutter_story_encoder 1.1.5

A production-grade, hardware-accelerated video export engine for Flutter. Specifically designed for high-scale social media story editors requiring premium performance, thermal stability, and 4K capability.

1.1.5

• iOS: Switched Pigeon to Swift generation to resolve scope visibility issues.
• iOS: Fixed CMSampleBufferCreateReady parameters for silent audio generation.
• iOS: Improved error handling by using PigeonError for better type compatibility.

1.1.4

• Android Hotfix: Fixed IllegalStateException: Can't write, muxer is not started by implementing track synchronization and muxer lifecycle safeguards.
• Improved Stability: Ensured that video and audio tracks are fully registered before the muxer begins writing sample data.

1.1.3

• Android Hotfix: Fixed unresolved program and textureId references in OpenGLRenderer.kt.
• Android Gradle Hotfix: Added settings.gradle to give the plugin's Android project a unique name, resolving IDE project collisions.
• Unit Tests: Corrected Pigeon mock implementation and fixed missing imports in flutter_story_encoder_test.dart.

1.1.2

• iOS Hotfix: Fixed color channel swap (Blue/Red) when encoding from Flutter raw RGBA frames.
• iOS Stability: Fixed potential crash by resetting memory pools between encoding sessions.
• Android Performance: Optimized silent audio track generation by reusing zero-buffers.

1.1.1

• Android Optimization: Implemented buffer reuse in OpenGLRenderer to eliminate frame-level allocations and reduce GC pressure during high-resolution exports.
• Improved Lifecycle: Properly shut down background executor on Android when plugin is detached.

1.1.0

• Commercial Grade Release: Refactored both platforms for hardware-accelerated production use.

• Audio Support: Added silent AAC audio track generation on iOS (AVFoundation) and Android (MediaCodec).

• iOS (AVFoundation): Implemented CVPixelBufferPool and requestMediaDataWhenReady for zero-allocation, thermal-stable encoding.

• Android (MediaCodec): Switched to Surface-based input with EGL/OpenGL ES for GPU-backed encoding.

• Improved API: Migrated to Pigeon for type-safe, high-throughput IPC.

• Unified Telemetry: Real-time stats (FPS, frames processed) streamed back to Flutter.

• Fixed Android @UiThread exception by ensuring progress updates and completion callbacks run on the main thread.

1.0.3

• Renamed Android package to com.lucasveneno.flutter_story_encoder.

1.0.2

• Fixed Android Kotlin compilation error ("Property must be initialized").

1.0.1

• Updated repository metadata and documentation.

1.0.0

• Initial release of the high-performance video export engine.
• Type-safe IPC implementation using Pigeon.
• iOS: Hardware-accelerated pipeline with AVAssetWriter and CVPixelBufferPool.
• Android: GPU-backed MediaCodec Surface encoding with EGL/OpenGL renderer.
• Real-time encoding statistics and progress callbacks.
• Support for 1080p and 4K @ 30/60fps.
• Thermal stability and backpressure management.
